Coal (35%) and gas (28.5%) still dominated in 2013. Some of the growth in renewable electricity was because of an increase in the amount of electricity generated by burning biomass in power stations. In 2011, energy company RWE Npower converted a coal-fired power station to woodpellets but this later closed due to issues over Government subsidies. Wind energy increase significantly partly due to opening of new installations but also because 2013 was a very windy year. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/266415/renewables.pdf https://www.carbonbrief.org/blog/2013/10/uk-renewable-generation-reaches-record-high-for-a-bit/
